A term used in the diagnosis of idiots by medical professionals. Often associated with people who have no sense of evolution or the evolving of mankind (and womankind) into a higher-functioning being (see also low-IQ and homophobes).

Doctor: "So, Mr. Dope, why are you afraid of homosexuals."
Patient: "Because the bible says they're wrong! It has to be true if the bible and the church say it's wrong! Just like women can't be priests and the sun revolves around the Earth!"
Doctor: "Oooookkkaaaay." (Writing in his chart. Diagnosis: Idiotism)
